 * Hello.
 * Since uploading my wordpress web to php 8.1, on my admin view the following messages
   appear and prevent me to use some features of other plugins. For other users 
   or non-logged visitors, it turns up to appear like a blue belt above the web 
   header.
 * I’ve been using BBB plugin for years and never had problems with it.
 * Please, can you help me or solve this one?
 * Thank you.
